Errors 1, 3, 7, 8, 9 are also common with traders. #1 can occur when commissions, spreads, option decay eat up most of the profits. #3 is about emotions, which for 90% of traders lead to losses. #7 is focusing too much on the tree, not enough on the forest, though for traders there is a balance there. #8 might be characterized as not knowing what we don't know, or over estimating our own knowledge. #9 chasing what is currently hot, is especially common with novices, but experienced traders also get swept up in the madness of crowd.

About Me

I now have two blogs, a piano blog
(link1)
and a stock market blog (link2).

Piano intro: I am a whistle and Irish flute player that started playing piano keyboard in March 2012. Mostly I compose and play my original tunes on my Casio PX-150 digital piano, which I bought in January 2013. I started in 2012 with a Yamaha NP11 keyboard.

Intro for trading blog: I am an individual investor posting a public trading diary. I am not here to give advice. I post my trades and thoughts for public consideration. Mostly it helps to keep myself straight. As of 2012, my favored trades are selling naked puts and strangles.
